I am buying a used powerbook g4 1.5ghz with 1.25gb ram. It has 60gb hd and combo drive. How can i find out the speed of the hard drive (4200 vs 5400 rpm)? PowerBook6,8 TOSHIBA MK6026GAX (this is the hd on the powerbook) Is this a good choice for basic stuff ( email,safari,itunes) and some movie stuff (isquint,ffmpegx)

I'm using Data Rescue III on a USB powered hard drive with and it's taking a very long time with my iMac G5... It says 42,291 hours remaining (about 5 years) If I did it on my Mac Pro would it go faster, or is the recovery speed based on the hard drive speed?

Has anyone gotten to the bottom of this thermal calibration error with the G5? I see lots of discussion of a possible bug in ASD thermal calibration and claims that it can destroy the eeprom that stores the calibration info on the logic board. So what's the bottom line here? Does this error in reality indicate that the eeprom is no longer writable? Could this simply be an issue of the inner door not sealed properly (perhaps this calibration is critically sensitive to this)?

The fans are racing as intended since the CPU's have been replaced and the calibration stored on the logic board is no longer correct. Everything is fully functional and passes all tests. The inner shield is in place and the sensor (by the rightmost tab) sees it there. The intake fan is running. I also tried another fan with no change. I suspect that some overly high sensitivity to the fan speed is not really the issue here. I have a dual 2.5GHz G5. The liquid cooling system is completely refurbished and the system passes ASD tests. I currently have ASD 2.5.8. I see reports of success using this version so there must be some hardware related issue here.

my hard drive stopped working and I want to know if there is any program to see what is wrong with it? Because it stopped working just on running process, I did not drop it or smth. And if i connect on another PC hard drive apears but I can not explore, it is alowed only to format.

If I run the hardware test, they can check possible errors on my hd? I remember on pc a soft in the 90s for check bad clusters on the hd, on Mac I know disk warrior, but I never use. Its necessary use disk warrior or something. I hear people that say that its bad.

I just bought as internal hard drive for my Mac Pro, to back up everything from the system drive. I was just wondering, the drive came through the post, it was well packaged, though is there was way of scanning it to see whether its 100% condition? Would I format it by in Disk Utility by clicking on the drive and pressing erase.

I was wondering if there was a way to check what is taking up your hard drive space. I have a 500GB drive and only have about 150GB left, and I really dont no why its that low...

I have a few movies on my computer (maybe about 20), but I cant see that taking 300GB...

I tried to just highlight everything, hoping a total file size would show, but I dont see one.

I just moved a bunch of video files that were about 1GB each onto an external, and it only cleared about 10Gb...But I have a feeling that iMovie might be the reason, as most of those video files were imported into iMovie. If thats the case, how do I clear out iMovie?

I've been looking at a number of different Firewire 800 enclosures to use with my new Mac Mini and I have seen lots of complaints with almost all the enclosures that I have investigated, including the Newertech MiniStack v3 which I thought should be a good one. A recent enclosure I came across that I haven't seen any bad reviews about is the Icy Dock (MB559UEB-1S). I'd like to know if others are using this and what they think about it. The next question has to do with the type of hard drive to put into the enclosure. Is it worth getting a high performance drive, or will the Firewire 800 interface be the bottleneck even with an average speed drive?

My G5 tower is one of the early models. Today I turned it on. Immediately the drive bay fan was running at maximum speed. The Mac's temperature was cold as it had not been used for 12 hours. So the speeding fan could not have been due to the drive bay being overheated. The fan never slows down. Even after a restart it immediately spins at its maximum. Plus it stays at maximum speed all the time.

My PowerBook G4 (Alum) died. I've had it for 4 years, taken it with me to Alaska and all over the lower 48, and have had nothing but happy experiences. I knew she was gonna go, but I was hoping she'd hold on until I could afford a MacBook. Alas, no. The problem appears to be the ability of the logic board to communicate with the hard drive. I can hear the HD spin, but even with Disk Warrior, I cannot locate it. The Mac Geniuses at my local Apple store confirmed this and gave me a shoulder to cry on. I've run Disk Warrior, Disk Utility, and tried finding it using the target disk mode - no luck.

The problem is that I've got 4 years of teaching materials, 6000 songs, and irreplaceable pictures on the HD, so I can't bring myself to just trash it. It's true that you only fail to back up you stuff once. This is my once. I've heard that with PC hard drives, you can just drop the old HD into a USB HD box and use it as an external HD. I can't afford professional data retrevial, and I want to give this option a try if it'll work with a Mac HD. Any ideas or suggestions?

Alright, here's the situation. Last week I shut down my computer to go away for thanksgiving, and when I came back and turned on my 20" white intel imac my hard drive fan sounds like it is going max rpm. I have istat pro installed and the rpm for the HDD fan is showing it's at zero. Does anybody have a clue as to why this is happening? My computer was working fine when I last used it but now my fan is going crazy. It's really loud and i'm concerned my the life of my fan. Any suggestions on what to do would be great. I installed Snow Leopard after the problem occured, but it's still happening.

I spent two weeks obsessing on what type of drive to put in my new 8-core Mac Pro (january 2008). I was all set on spending $$$ and go with two 1-TB Samsung's but at the last minute I read this:

[URL] which posted better World Bench ratings than a 10k Raptor and is quieter than WD's Green drives - NewEgg had been out of stock of this brand new drive and suddenly got a batch in and I ordered two of these (WD Caviar 640 Gig / 16 meg cache w/only 2 drive plates). This drive is LIGHTNING fast....I've got before and after bench marks to post, I went from a 56.84 to a 102.91! Also, these installed so easily - not a single hitch!

Recently I bought WD6400AAKS hard drive. I made to partitions (1st for OS and applications, 2nd one for photo files). I also did fresh OS install and loaded basic applications. Strangely I didn't notice any speed boost while booting and to be honest I feel like all applications (photoshop for example) are also starting much slower than on original hdd. Is there any way to test hard drive if it performs as it should be? I also have 2 more older drives installed. is it possible that one of them would slow the system down?

I own a 1st generation MacBook Core Duo (black) with 80GB Fujitsu at 1.5 Gigabit/s. I want to replace this with a compatible hard drive. Will this - Western Digital Scorpio Blue WD3200BEVT 320GB 5400 RPM 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive - work in my laptop? I notice that it has a 3.0Gb/s speed versus my current Fujitsu 1.5Gb/s. I'm using Tiger, if this matters.

I know this topic has been gone over several times, but I'm still having trouble deciding on which to get in a new 15", 2.8Ghz MBP - 5400/500GB, or 7200rpm/320GB (or 500, really). I'll be using the machine largely for graphic design, but also for various other tasks as my main computer. I've heard the faster drive IS a noticeable difference, but it also drains battery life and runs hot. There doesn't seem to be a consensus on this anywhere. Is the 7200 worth it?

I am desperately waiting on the MacBook Pro refresh. I plan on buying my first MBP, a major upgrade from my grandma's iBook G4 I am currently using. I had a question about hard drive speed. I know that 7200RPM is quite a bit faster than 5400RPM, but what about battery life. I need it to get me through a day of school, 4-8 hours. My question to you is: would it be worth the extra $50 or so to upgrade to a 7200RPM HD, and what would the effects on battery life be? In your own experiences with current MBPs. I've thought about going with a SSD, but that might end up being too much, since I'm already paying quite a bit.

I have a new macbook pro and after reading various threads I want to buy a gtech 320gb external drive. The only one I can track down is the firewire400. (at a reasonable price) The MB is FW800. will the FW400 work OK and is the speed significantly slower?

I just switched out my 160GB hard drive on my 13" MBP for a 500GB. I do notice that things are a little slower now as far as opening up apps and such. Would upgrading to the 4GB of RAM instead of the 2 I have make a difference or is that the trade i get for running a 5200 500GB HD.

I have an early 2009 macbook, with 320 GB hard drive and running OS Lion, after i upgraded my os to lion, the computer ran perfectly normal, although a little bit slower than running snow Leopard. However, recently I notice my mac become very slow, got rainbow wheel even when i open the safari. then I use the black magic to test the hard disk speed, it appears the read and write speed is only a little over 30mb/s.

i have recently change my keyboard at apple store, I notice my mac slow down after that, do you think it would related?

What is the quickest way to check my internet connection speed in Tiger?On a PC, I've always known it's as simple as hovering the cursor over the connection icon in the taskbar. It's been like that at least since XP if not earlier.In OSX though (Tiger at least) the Airport icon in the menubar doesn't give any of that information.
